Brief Summary:
The purpose of this clinical trial is to determine whether the combination of 5-fluorouracil (5-FU) plus a DAVANAT (carbohydrate polymer) along with Avastin and Leucovorin (LV) is beneficial in treating colorectal cancer in patients unable to tolerate intensive chemotherapy.

Condition or disease Intervention/treatment Phase
Colorectal Cancer Drug: GM-CT-01 Drug: 5-Fluorouracil, Leukovorin, bevacizumab Phase 2

Detailed Description:
This is a Phase II, multi-center study of DAVANAT which has been shown to increase the anti-tumor activity of 5-FU in mice. 5-FU is a chemotherapy drug commonly used to treat tumors. A Phase I study of 40 patients showed that DAVANAT in different doses plus 5-FU was well tolerated in patients with different types of solid tumors who failed standard, approved treatments.

Arm Intervention/treatment
Experimental: GM-CT-01 Drug: GM-CT-01
On Day 1 and 2 of each cycle, GM-CT-01 280 mg/m2 administered IV over 30 minutes with 5-FU (400 mg/m2), followed by a 22-hour continuous infusion of GM-CT-01 (280 mg/m2) with 5-FU (600 mg/m2 .)
Other Name: DAVANAT

Drug: 5-Fluorouracil, Leukovorin, bevacizumab
On Day 1 and 2 of each cycle, LV (200 mg/m2) will be administered IV over 2 hours, followed by 5-FU 400 mg/m2 in solution with GM-CT-01 280 mg/m2 administered over 30 minutes, followed by a 22-hour continuous infusion of GM-CT-01 (280 mg/m2) and 5-FU (600 mg/m2 ). on Day 3 Avastin® (5 mg/kg)will be given IV over 30 to 90 minutes per the package insert.
Other Name: 5-FU, LV, Avastin®

Primary Outcome Measures :
  1. Primary Outcomes: Assess the efficacy and safety of GM-CT-01 administered with 5-FU, LV, and Avastin® in the first-line treatment of unresectable, locally advanced, and/or metastatic CRC. [ Time Frame: When 17 evaluable patients will complete the study ]
    To assess the clinical benefit of a regimen of GM-CT-01/5-FU, LV plus Avastin® when administered intravenously as a first-line treatment to patients with Stage III or IV ,advanced or metastatic CRC. Clinical activity will be assessed by determining the percentage of subjects exhibiting an objective response (complete response [CR]) plus partial response [PR]). Tumor response will be assessed following Response Evaluation by RECIST guidelines.

Secondary Outcome Measures :
  1. To evaluate the safety of the DAVANAT®/5-FU, LV plus Avastin® regimen. [ Time Frame: Throughout the study and when 17 evaluable patients will when complete the study ]
    Assess safety of regimen and also patient reported outcomes using a Quality of Life (QoL) instrument.

  2. Explore progression-free survival (PFS) and survival [ Time Frame: When at least 17 evaluable patients complete the study ]
    To explore time to tumor progression, duration of response and and survival at 6 and 12 months after the first dose of study drug.
